Pin 18 is slid inwardly by m'eansof an operating arm 88 riveted to a tube 84. The inner end of tube 84 is slideably supported by a collar bracket 86 welded to the burner a collar portion snugly receiving the end of the tube. Referring to Figure 1, tube 84 extends from the burner to the front of the refrigeratorcabinet and has its outer end slideably carried by a bracket 90 mounted upon the lower wall of 'the refrigerator cabinet. Welded to the outer end of tube 84 is an operating handle 82 which carries at its top a guide pin 94 the righthand end of which is slideably received in .an

opening in bracket ,90: A compression spring 9 6 is coiled about tube 84 between bracket 98 and operating handle 92, and at the right of bracket 90 and welded to tube 84 is a collar 98. Spring 96' tends to slide the tube to the left, and collar 98 limits the movement so that the tube is normally held in the position shown. However, handle 92 is so spaced from bracket 90 that the two may be grasped, and by squeezing the handle and the bracket, the tube is slid to the right against the action of spring 96 with the result that pin 18 displaces yalve ball 14 (Figure 3) from its seat and gas is supplied to jets 62 and 64.

Jet 64 is directed into the ,open end of tube 84, and when the tube is moved to the right, its

, end is adjacent the jet. Thus, gas from the jet passes through tube 84 where is mixes with air,

;and the mixture emanates through the front end of the tube. This mixture is ignited by holding a flame at the front end of the tube adjacent handle 92, and the flame will immediately travel back through the tube, and at the rear of the tube the gas from jets 62 and 64 is ignited. Due

to the fact that flames are maintained at the jets, no more gas passes through tube 84, but the flames extend upwardly (Figure 2) so as to heat the thermostatic diaphragm ll. When the thermostatic diaphragm is sufficiently heated, it snaps to the right and opens valve l5 so as to supply gas to the main burner. As this gas passes from openings 48, it is ignited by the flame from jets 62 and 64; Handle 92 (Figure 1) is then released so that valve ball I4 is reseated, shutting on the supply of gas tothe igniting burner.
